Abstract
The danger of life of human being is
increasing with advancement of scientific
development in different fields. The security of
industry (Steel Melting industry) is important to
human life. The security system can detect
abnormal and dangerous situation and notify us.
In this paper, Virtual Instrumentation based
intelligent Surveillance system that contains an
obstacle avoiding robot which we can monitor and
control the hazardous and inaccessible places to
humans, is presented.
Keywords- security, sensor, virtual instrument.
I. Introduction
With tremendous growth of industries,
there has been equal growth in industrial accidents.
The importance of industrial safety was realized
because millions of accidents occur which results
in either death or disablement of employees and
involve large amount of losses resulting from
danger to property and men. Most cases of such
show the lack of proper surveillance systems to
notify the disaster in industries.
Unnoticed gas leaks, unnoticed smoke
ejecting from industries, gas combiners etc., have
seen devastating outcomes, due which there has
been significant damage to the mankind. The main
reason attributed to such situations is poor
surveillance systems which often fail to monitor the
conditions.
The disadvantages of the traditional
instrumentation technology for monitoring
conditions are
 These systems are fixed, (mobile monitoring
is absent)
 These systems can do only one task (single
sensor). Hence, need different systems for
different purpose of detection
 They bank on portable display which is
attached with the system
 They cannot be accessed from remote
locations
To overcome the problems of traditional
surveillance system a Virtual Instrumentation based
Surveillance system is developed through which
we can monitor and control the hazardous and
inaccessible places to humans. The proposed multi-
sensory security system is designed to have 4
sensors, it is provided with 2 wheels to provide
continuous unmanned monitoring of
 Gas leakages
 sudden changes of temperature
 obstacle avoidance
 Smoke ejection.
and notifying through a wireless ZIGBEE module
on a LABVIEW graphical interface.
The GENIE system offers flow chart
microcontroller programming and simulation as
well as full integration with circuit wizard.
GENIE Microcontrollers can be
programmed using flowcharts. Flowcharts show
the steps that will be followed by microcontroller
when one’s program is running. Flowcharts are
drawn by selecting particular commands and then
linking them together.

Genie design studio has been used to
program microcontroller for obstacle avoidance
and the programmed flow chart for obstacle
avoidance is shown below

Lab VIEW is an integral part of virtual
instrumentation because it provides an easy-to-use
application development environment designed
specifically with the needs of engineers and
scientists in mind. Lab VIEW offers powerful
features that make is easy to connect to a wide
variety of hardware and other software. One of the
most powerful features that lab VIEW offers
engineers and a scientist is its graphical
programming environment. With Lab VIEW, one
can design custom virtual instruments by creating a
graphical user interface on the computer screen
through which one
 Operate the instrumentation program
 Control selected hardware
 Analyze acquired data
 Display.
Fig.1.3. Block diagram ZIGBEE
The four sensors are connected to the
microcontroller, whose functioning is determined
by flow chart programming, implemented through
GENIEE design studio. And output is wirelessly
transmitted by ZIGBEE modules and is accessed
through LABVIEW graphical interface.
The heart of this paper is PICf88 which has 5
analog to digital output pins. The robot made here
can detect the sudden changes in temperature such
that it displays the value in centigrade on
LABVIEW graphical interface. The circuit used
here consists of a thermistor, its primary
characteristic is its ability to alter its electrical
resistance in response to changes in case
temperature. It can be used to measure temperature,
or to sense temperature changes and compensate
for the temperature changes.
The obstacles that come in the middle of
the path are avoided and the collision of the objects
is prevented. For this L293d motor driver is used
which gives the specified movement to the wheels
whether in clockwise direction or anti clock wise
direction.
The harmful gases leaking from the industries are
detected and specified to us whether any harmful
gas is present, .the gas sensorMQ6 present in the
gas detection circuit plays the major role for
identifying the gas whether dangerous gases are
present. Smoke produced by a fire affects the
intensity of a light beam passing through air. The
smoke can block or obscure the beam. The light
emitted by LED falls on IDR, if the smoke passes
between them the blocking of light happens thus
the smoke particles are observed.
The final values from all the components
outputs are collected by the ZIGBEE which acts
as serial port.
A gas detector is used to detect a gas leak
and interface with a control system so a process can
be automatically shut down. A gas detector can
also sound an alarm to operators in the area where
the leak is occurring, giving them the opportunity
to leave the area.

An MQ-6 gas sensor is applied in the gas
sensor module. As per its datasheet, it has great
sensitivity to propane, butane, isobutene, and LPG
and all-natural gas. The sensor can also be

implemented to detect combustible gases,
especially methane.
When smoke particles partially block the light
beam, the reduction in light reaching the
photosensitive device alters its output. The change
in output is sensed by the detector’s circuitry, and
when the threshold is crossed, an alarm is initiated.
Obscuration type detectors are usually of the
projected beam type where the light source spans
the area to be protected.

The objective of the competition would be
for the robot to reach the target in the shortest time.
Autonomous robotic vehicle guidance for indoor
navigation has been developed for Mobile
Industrial Robot model. The resulting design will
navigate the environs in a building without the
need of human intervention. The guidance system
consists of infrared sensors for avoidance. It can
detect the obstacles within the range 10 to 80 cm.
This paper represents mainly on software
implementation of obstacle detection and
avoidance system for Wheeled Mobile Robot. This
system consists of infrared sensors and
microcontroller.
Fig. 1.6. obstacle avoidance robot
In this system three infrared sensors are
used for left, front and right. In this robot system,
the input signal is received from sensor circuit and
PIC is operated according to the received sensor’s
signal. This robot if it senses the obstacle through
the sensors will drive the motors in the alternative
right turn until it detects the clean path. Here the
comparator will set the reference point for the input
signal which will help the controller to get strong
input signal.
Temperature is one of the most common
real-world characteristics that systems need to
measure. Many industrial processes, from steel
manufacturing to semiconductor fabrication,
depend on temperature. Thermistors are available
in several package types. The most common
package is a disk, although they are also available
with axial leads and can be purchased as chip or
Metal Electrode Leadless Faces (MELF)
components for surface mount applications.
Selection of packaging style depends on the
application and where the temperature
measurement needs to be made Surface.
II. ZIGBEE WIRELESS MODULES
ZigBee is the name of a specification for a
suite of high level communication protocols using
small, low power, low data rate digital radios based
on the IEE 802.15.4 standard for wireless personal
area network (WPANs), such as wireless
headphones connecting with cell phones via short
range radio. The technology is intended to be
simpler and cheaper than other WPANs, such as
Bluetooth. ZigBee is targeted at radio-frequency
(RF) applications which require a low data rate,
long battery life and secure networking.
ZIGBEE enables broad-based deployment
of wireless networks with low-cost, low-power
solutions. It provides the ability to run for years on
inexpensive batteries for a host of monitoring
applications: Lighting controls, AMR (Automatic
Meter Reading), smoke and CO detectors, wireless
telemetry, HVAC control, heating control, home
security, Environmental controls and shade
controls, etc.
